Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56666, here are decompositions:

3 + 56663 = 56666
7 + 56659 = 56666
37 + 56629 = 56666
67 + 56599 = 56666
97 + 56569 = 56666
139 + 56527 = 56666
157 + 56509 = 56666
163 + 56503 = 56666

Showing the first eight; more decompositions exist.
